  • Руками(?) в пакетах мы переносим всё из /bin, /sbin в соответстующие /usr/bin и /usr/sbin и создаём Provides со старым путём.
  • rpm должен сам создавать симлинк. Если есть Provides /bin/sh и файл /usr/bin/sh, то создаём ссылку /bin/sh -> ../usr/bin/sh.
  • После того как в /bin не останется ничего кроме ссылок на /usr/bin, в пакете filesystem можно менять /bin на симлинк.
  • Пока пакет filesystem не обновился, мы находимся на стадии постепенной подготовки, замещая файлы в /bin автоматическими ссылкам.
  • Чтобы filesystem заменить каталог на ссылку нам нужно удалить каталог в %pretrans. В этом случае конфликта не должно быть. From rpm handleRemovalConflict():
...but if the conflicting item is either not on disk, or has
already been changed to the new type, we should be ok afterall.
